Improve your health with an approach grounded in science and centered around dietary, lifestyle and natural healthcare solutions. You can feel better! We are happy to help.

Practical, Effective

Functional Health

We understand feeling sick and frustrated. You feel like you’ve tried everything, yet nothing seems to work. Perhaps your doctor doesn’t have the time or experience to offer you more than a prescription, or maybe you’ve seen a naturally-minded doctor who was unable to fully help.

With our decades of experience, we understand the causes of your symptoms and help you implement a personalized plan using a science-guided, natural approach.

Whether you’ve been sick for a long time or are simply looking to live your healthiest life, Dr. Ruscio, DC and his team of providers are here to partner with you to improve your health.

Why People Choose Us?

Put simply, because we strive to get you well, quickly and cost effectively. Integrative and functional health has become overly costly and often involves unnecessary testing and treatment, thus wasting a significant amount of a patient’s time and money. Additionally, some of the most popular tests and treatments used in this field are based on dogma, and not on sound science. This is why we’re committed to conducting research at the clinic in addition to treating patients.
